MIL-C-26482 Power (3kV DC) standard PS-MCF series


Hermetic Sealing Power P-MCF series (Power-Standard Multi Contact Feedthrough) are available with commercial bayonet style connection on air side and threaded connection on vacuum side.

This standard configuration provides a typical connection, compatible with MIL-C-26482 standard.

The particular design provides an high voltage insulation (tested up to 4 kV DC), a feature not not found on other brands.

Our own special sealing process, with the use of high quality techno polymer as insulator, gives superior electrical insulation and ultra-high vacuum tightness.

The feedthroughs are highly resistant to thermal and mechanical shocks.
